I will test the behaviour of EHCache using the Disk Overflow and
give you a feedback on this.
JBoss Cache 1.x and 2
This won't be compilable at the same time.
Yup. But JBoss 4 uses 1, and JBoss 5 uses 2. And from my
experimentation you can't use 1 in JBoss 5 or 2 in JBoss 4.
How shall I provide this, because I would break the build.
Dunno ;-) Thats part of the challenge. However we definitely need to
support both.
I will provide the abstraction for the Pojo as well, though I do not
perfectly see the need. It is slower than the normal JBoss Cache
(alias TreeCache).
Because we already support it?

Sebastian
